## 📄 Com. v. Smith, J. ✍️ McLaughlin 🏛️ CourtListener · 📅 2026-04-10 --- The Pennsylvania Superior Court, on remand from the state supreme court, held that the evidence was still sufficient to sustain James Smith's unlawful-contact-with-a-minor convictions after Commonwealth v. Strunk narrowed the statute's scope. The court said Smith's verbal directions to the child victims immediately before the assaults counted as communications that furthered sexual exploitation, which is the key line Strunk requires. **🔑 Key Findings:** - The court reaffirmed Smith's judgment of sentence after a remand to reconsider the unlawful-contact counts under Strunk. - Strunk was read as an anti-grooming and facilitation rule, not a broad ban on all abusive physical contact. - Smith's statements telling victims to perform oral sex and directing one victim to lie on a table were treated as qualifying communications under 18 Pa.C.S. § 6318. - The opinion distinguishes cases with no communicative act from cases where speech or instructions reposition a victim to enable the assault. - The ruling tightens the doctrinal line around when grooming-style or facilitative communication is enough to support unlawful-contact charges. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10840888/com-v-smith-j/) #law #court-opinion #child-safety #criminal-law ⏱️ 2026-04-10 23:32 UTC

## 📄 GRAFHEN is not IND-CPA secure ✍️ Remi Geraud-Stewart 🏛️ IACR ePrint · 📅 2026-04-09 --- A very short but sharp cryptanalysis note: this paper shows the recently proposed noise-free homomorphic encryption scheme GRAFHE/GRAFHEN fails basic IND-CPA security. The author provides an efficient distinguisher, which means the scheme is broken at a foundational confidentiality level rather than just weakened at the margins. **🔑 Key Findings:** - Targets a recently proposed noise-free fully homomorphic encryption construction based on rewriting systems in symmetric groups. - Provides an efficiently computable distinguisher against the scheme. - Breaks IND-CPA security, a baseline confidentiality notion for public-key encryption. - Implies the construction is not suitable as proposed for secure FHE use. - Illustrates the fragility of novel algebraic cryptosystems when security arguments are incomplete. --- 🔗 [Read paper](https://eprint.iacr.org/2026/700) 📎 [PDF](https://eprint.iacr.org/2026/700.pdf) #cryptography #crypto #homomorphic-encryption #cryptanalysis ⏱️ 2026-04-11 20:47 UTC

The result is a cleaner path to scalable recursive proof composition, and the authors use it to build the first CCA1-secure multi-hop FHE and the first adaptive multi-hop aggregate signatures from LWE. **🔑 Key Findings:** - Gives the first merge procedure for SNARGs that supports an unbounded polynomial number of recursive merges with arbitrary topology. - Improves the security reduction so it depends on merge depth rather than total tree size, which can be exponentially larger. - Applies to trapdoor languages, where a hidden trapdoor is only needed in the proof of security, not by provers or verifiers. - Provides constructions from sub-exponential indistinguishability obfuscation and from LWE, with different compactness tradeoffs. - Uses the framework to obtain the first CCA1-secure multi-hop FHE and the first adaptive multi-hop aggregate signature scheme from LWE. --- 🔗 [Read paper](https://eprint.iacr.org/2026/678) 📎 [PDF](https://eprint.iacr.org/2026/678.pdf) #cryptography #crypto #fhe #snargs #lwe ⏱️ 2026-04-08 20:45 UTC

## 📄 SPLASH: Runtime-Configurable and Comprehensive Speculative Execution Attack Mitigation in Post-Silicon Microprocessors ✍️ Sungbum Kwon, Jaejin Lee, Hyeran Jeon, Mohammad Abdullah Al Faruque 🏛️ IACR ePrint · 📅 2026-04-07 --- SPLASH proposes a post-silicon defense framework for speculative execution attacks that can be reconfigured after deployment instead of being locked into narrow, hardwired mitigations. It combines speculative information-flow tracking with a programmable control table, letting operators tune how speculation is constrained across processor structures while keeping performance impact low. **🔑 Key Findings:** - Introduces Speculative Information Flow Tracking (SIFT) to trace how speculative data propagates through microarchitectural components. - Adds a reconfigurable speculative table that can enforce runtime-adjustable security policies across the processor pipeline. - Supports post-fabrication policy changes, including speculative window tuning and selective protection of specific structures, without redesigning hardware. - On small and medium BOOM processors, the authors report that SPLASH mitigates all evaluated speculative execution attack classes. - Average runtime overhead is reported as 0.05% on small BOOM and 1.23% on medium BOOM, substantially lower than prior leading defenses. --- 🔗 [Read paper](https://eprint.iacr.org/2026/677) 📎 [PDF](https://eprint.iacr.org/2026/677.pdf) #hardware-security #cybersecurity #privacy #cryptography ⏱️ 2026-04-08 14:45 UTC

## 📄 From Hallucination to Structure Snowballing: The Alignment Tax of Constrained Decoding in LLM Reflection ✍️ Hongxu Zhou 🏛️ arXiv · 📅 2026-04-07 --- This paper examines whether constrained decoding alone can make LLM self-reflection more reliable, without external critics or extra training. Instead of fixing reasoning failures, the study finds that strict structure requirements can create a new failure mode, where the model over-optimizes for format and misses semantic mistakes. **🔑 Key Findings:** - In open-ended reasoning, unconstrained self-correction failed through recursive justification of early errors, which the author calls hallucination snowballing. - Imposing Outlines-based structural constraints on Qwen3-8B did not improve self-correction performance. - The constrained setup introduced a distinct failure mode, structure snowballing, where formatting demands trapped the model in superficially valid but semantically weak reflections. - The paper frames this as an alignment tax: stronger syntactic control can consume model capacity that would otherwise go toward genuine error detection and correction. --- 🔗 [Read paper](https://arxiv.org/abs/2604.06066v1) 📎 [PDF](https://arxiv.org/pdf/2604.06066v1) #ai-security #cs.CL ⏱️ 2026-04-08 06:03 UTC

The paper’s main value is comparative: it argues Kimi is competitive with frontier models on dual-use capability while being noticeably more permissive on some dangerous request classes. **🔑 Key Findings:** - Evaluates CBRNE misuse risk, cybersecurity risk, misalignment, censorship, bias, and harmlessness. - Finds dual-use capability roughly comparable to GPT-5.2 and Claude Opus 4.5 in several areas. - Reports significantly fewer refusals on CBRNE-related prompts than those comparison models. - Finds competitive cyber performance but not frontier-level autonomous offensive capability in vulnerability discovery/exploitation. - Reports concerning sabotage ability, self-replication propensity, and narrow political censorship, especially in Chinese. --- 🔗 [Read paper](https://arxiv.org/abs/2604.03121v1) 📎 [PDF](https://arxiv.org/pdf/2604.03121v1) #ai-security #cybersecurity #law #csCR #csAI #csCL ⏱️ 2026-04-06 06:00 UTC

## 📄 SentinelAgent: Intent-Verified Delegation Chains for Securing Federal Multi-Agent AI Systems ✍️ KrishnaSaiReddy Patil 🏛️ arXiv · 📅 2026-04-03 --- SentinelAgent proposes a formal framework for verifying who authorized what across multi-agent delegation chains, with deterministic enforcement for scope narrowing, policy preservation, traceability, and cascade containment. The interesting wrinkle is that the paper treats intent verification as inherently probabilistic, then shows the rest of the chain can still be made mechanically auditable and hard to abuse. **🔑 Key Findings:** - Defines a Delegation Chain Calculus with seven properties covering authorization narrowing, policy preservation, forensic reconstruction, and output conformance. - Uses a non-LLM Delegation Authority Service to enforce the protocol at runtime. - Reports 100% combined TPR at 0% FPR on DelegationBench v4 across 516 scenarios and 10 attack categories. - Blocks 30/30 black-box adversarial attacks in its evaluation while deterministic properties remain mechanically verified. - Shows intent verification is the weak link under paraphrasing, but other controls still constrain abuse to traceable, policy-compliant actions. --- 🔗 [Read paper](https://arxiv.org/abs/2604.02767v1) 📎 [PDF](https://arxiv.org/pdf/2604.02767v1) #cybersecurity #ai-security #intelligence #agents #csCR #csAI #csMA ⏱️ 2026-04-06 06:00 UTC

The authors call this unintentional cross-user contamination (UCC) and show it remains a serious problem even when systems try to sanitize shared memory. **🔑 Key Findings:** - Formalizes UCC as a distinct failure mode separate from adversarial memory poisoning. - Defines three contamination types and evaluates them across two shared-state mechanisms. - Reports contamination rates of 57-71% under raw shared state from ordinary benign interactions. - Finds write-time sanitization helps for conversational memory but leaves substantial residual risk for executable artifacts. - Warns that failures often surface as silent wrong answers rather than obvious leakage events. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01350v1) 📎 [PDF](https://arxiv.org/pdf/2604.01350v1) #ai-security #privacy #cybersecurity #cs.CL #cs.AI #cs.CR ⏱️ 2026-04-06 00:03 UTC

## 📄 AgentSocialBench: Evaluating Privacy Risks in Human-Centered Agentic Social Networks ✍️ Prince Zizhuang Wang, Shuli Jiang 🏛️ arXiv · 📅 2026-04-01 --- AgentSocialBench looks at privacy leakage in multi-agent social settings where assistants coordinate across users, domains, and ongoing relationships. The paper argues this setting is qualitatively harder than single-agent privacy evaluation, then shows that even explicit privacy instructions can backfire by encouraging agents to talk around sensitive material rather than avoid it. **🔑 Key Findings:** - Introduces the first benchmark focused on privacy risk in human-centered agentic social networks. - Covers seven scenario categories with hierarchical sensitivity labels and directed social graphs. - Finds cross-domain and cross-user coordination create persistent leakage pressure even with privacy-focused prompting. - Identifies an "abstraction paradox" where privacy instructions can make agents discuss sensitive material more, not less. - Concludes that prompt engineering alone is not enough for safe real-world agent-mediated social coordination. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01487v1) 📎 [PDF](https://arxiv.org/pdf/2604.01487v1) #ai-security #privacy #cs.AI #cs.SI ⏱️ 2026-04-06 00:03 UTC

## 📄 SelfGrader: Stable Jailbreak Detection for Large Language Models using Token-Level Logits ✍️ Zikai Zhang, Rui Hu, Olivera Kotevska, Jiahao Xu 🏛️ arXiv · 📅 2026-04-01 --- SelfGrader proposes a lightweight jailbreak detector that reads token-level logit patterns instead of relying on generated text or heavyweight internal probes. The core idea is to turn safety assessment into a compact numerical grading task, which makes detection faster, cheaper, and less sensitive to generation randomness. **🔑 Key Findings:** - Uses logit distributions over a small set of numerical tokens as an internal harmfulness signal. - Scores queries from both maliciousness and benignness perspectives to reduce false positives. - Avoids dependence on full textual outputs, which makes detection more stable under stochastic generation. - Reports up to 22.66% ASR reduction on LLaMA-3-8B versus compared baselines. - Cuts memory overhead by up to 173x and latency by up to 26x in reported experiments. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01473v1) 📎 [PDF](https://arxiv.org/pdf/2604.01473v1) #ai-security #cybersecurity #cs.CR #cs.AI ⏱️ 2026-04-06 00:03 UTC

## 📄 THED: Threshold Dilithium from FHE ✍️ Jai Hyun Park, Alain Passelègue, Damien Stehlé 🏛️ IACR ePrint · 📅 2026-04-01 --- THED turns Dilithium into a threshold signature scheme without changing the verifier: the output still validates under ordinary ML-DSA verification. The real contribution is the engineering needed to make FHE-backed threshold signing less absurd, including new homomorphic comparison tools and a more compact CKKS threshold decryption method. **🔑 Key Findings:** - Constructs a threshold Dilithium scheme whose signatures verify under the standard Dilithium/ML-DSA algorithm. - Uses threshold FHE, mainly CKKS, to evaluate most of signing homomorphically while keeping the challenge computation in the clear. - Introduces new tools for modular operations and homomorphic comparison across CKKS/BFV-style representations. - Adds a more communication-efficient threshold decryption method for CKKS. - Proof-of-concept reports 1.343s total FHE runtime on an RTX-5090 GPU, shrinking to 0.202s online with 4.10KB communication per party after preprocessing. --- 🔗 [Read paper](https://eprint.iacr.org/2026/638) 📎 [PDF](https://eprint.iacr.org/2026/638.pdf) #cryptography #crypto ⏱️ 2026-04-04 03:09 UTC

The proposed framework partitions large transaction graphs into distributed components and claims better efficiency and stronger pattern detection for complex laundering behavior in unsupervised settings. **🔑 Key Findings:** - Introduces ReDiRect, an unsupervised framework for exposing laundering patterns in large transaction graphs. - Uses fuzzy partitioning to break massive financial graphs into smaller distributed workloads for faster processing. - Proposes a refined evaluation metric meant to better capture whether meaningful laundering structures were actually surfaced. - Benchmarks on the Libra dataset and IBM synthetic datasets reportedly outperform prior and state-of-the-art approaches. - Positions excessive false positives from rigid rule systems as a core operational weakness the graph approach is meant to reduce. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01315v1) 📎 [PDF](https://arxiv.org/pdf/2604.01315v1) #fincrime ⏱️ 2026-04-04 00:03 UTC

## 📄 ClawSafety: "Safe" LLMs, Unsafe Agents ✍️ Bowen Wei, Yunbei Zhang, Jinhao Pan, Kai Mei, Xiao Wang, et al. 🏛️ arXiv · 📅 2026-04-01 --- This paper shifts safety evaluation from sterile chat benchmarks to the messier reality of local AI agents with filesystem and tool access. The authors build a benchmark around realistic prompt-injection paths and show that model safety depends heavily on the full agent stack, not just the base model. **🔑 Key Findings:** - Introduces CLAWSAFETY, a benchmark with 120 adversarial scenarios spanning software, finance, healthcare, law, and DevOps workspaces. - Tests three realistic injection channels: workspace skill files, trusted email, and web pages encountered during normal agent use. - Across 2,520 sandboxed trials, attack success rates ranged from 40% to 75% depending on model and scaffold. - Skill-file injections were consistently the most dangerous, suggesting trusted local context is a larger problem than generic web content. - Cross-scaffold experiments show safety outcomes vary materially with framework design, so evaluating only the backbone model misses the real risk surface. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01438v1) 📎 [PDF](https://arxiv.org/pdf/2604.01438v1) #ai-security #cybersecurity ⏱️ 2026-04-04 00:03 UTC

## 📄 PrivHAR-Bench: A Graduated Privacy Benchmark Dataset for Video-Based Action Recognition ✍️ Samar Ansari 🏛️ arXiv · 📅 2026-04-01 --- PrivHAR-Bench is a benchmark for the privacy-utility tradeoff in video action recognition, which the field badly needs because most papers still pretend privacy is a binary switch. Here the dataset provides multiple parallel privacy tiers so degradation can be measured instead of guessed. **🔑 Key Findings:** - Builds 9 privacy tiers for each source video, from lighter obfuscation to stronger cryptographic-style transformations. - Includes background-removed variants, pose keypoints, bounding boxes, and standardized splits for more comparable evaluation. - Baseline R3D-18 accuracy falls from 88.8% on clear video to 53.5% on the strongest encrypted/background-removed tier. - Cross-domain accuracy collapses to 4.8%, which is a useful reminder that privacy transforms and generalization do not magically coexist. --- 🔗 [Read paper](https://arxiv.org/abs/2604.00761v1) 📎 [PDF](https://arxiv.org/pdf/2604.00761v1) #privacy #computer-vision #cybersecurity #cs.CV #cs.CR ⏱️ 2026-04-02 18:10 UTC

WARP pushes repair deeper into Transformer internals by turning first-order logit-gap repair constraints into a tractable quadratic program, which is a lot less magical and a lot more useful. **🔑 Key Findings:** - Optimizes over inner-layer parameters while enforcing positive-margin, remain-set preservation, and certified robustness constraints. - Uses sensitivity-based preprocessing to keep the repair problem feasible across different encoder-only Transformer architectures. - Shows iterative optimization converges under mild assumptions to solutions satisfying the repair constraints. - Empirically improves adversarial robustness while retaining the promised repair guarantees in practice. --- 🔗 [Read paper](https://arxiv.org/abs/2604.00938v1) 📎 [PDF](https://arxiv.org/pdf/2604.00938v1) #ai-security #adversarial-ml #cybersecurity #cs.LG #cs.AI ⏱️ 2026-04-02 18:10 UTC

## 📄 Differentially Private Manifold Denoising ✍️ Jiaqi Wu, Yiqing Sun, Zhigang Yao 🏛️ arXiv · 📅 2026-04-01 --- This paper tries to make manifold denoising less of a privacy leak by treating the reference dataset as sensitive and spending privacy budget on local geometry estimates. In plain English: users get the geometric benefit of the secret dataset without simply being handed the secret dataset. **🔑 Key Findings:** - Uses private local mean and tangent estimation with iterative correction steps under (ε,δ)-DP accounting. - Separates DP-protected geometry estimation from budgeted query-point updates, which is at least architecturally sane. - Provides non-asymptotic utility guarantees under standard manifold assumptions relating error to sample size, noise, bandwidth, and privacy budget. - Targets downstream tasks like clustering, embedding, and visualization while preserving formal privacy guarantees for the reference data. --- 🔗 [Read paper](https://arxiv.org/abs/2604.00942v1) 📎 [PDF](https://arxiv.org/pdf/2604.00942v1) #privacy #ai-security #cybersecurity #cs.LG #cs.CR ⏱️ 2026-04-02 18:10 UTC

The interesting bit is the attempt to make policy evolution auditable instead of letting the controller quietly drift into unsafe behavior. **🔑 Key Findings:** - Per-switch PPO agents handle immediate mitigation while an LLM governance engine proposes validated policy-constitution updates. - Reported gains: +9.1% Macro-F1 over PPO and +15.4% over static baselines under heterogeneous attack conditions. - Worst-case degradation drops 36.8%, controller backlog peaks drop 42.7%, and RTT p95 inflation stays below 5.8% during heavy attacks. - Policy evolution converges within five governance cycles, cutting catastrophic overload from 11.6% to 2.3%. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01127v1) 📎 [PDF](https://arxiv.org/pdf/2604.01127v1) #cybersecurity #ai-security #defense #cs.CR ⏱️ 2026-04-02 18:10 UTC

## 📄 Kurdistan Victims Fund v. Kurdistan Regional Government ✍️ Judge Randolph D. Moss 🏛️ CourtListener · 📅 2026-04-01 --- This District of Columbia opinion dismisses a sprawling suit accusing the Kurdistan Regional Government and related officials of murder, torture, corruption, and other abuses because the pleadings never tied specific defendants to specific actionable conduct. The court holds that three successive complaints failed basic Rule 8 and Rule 12 standards, while also rejecting the fund's attempt to pursue thousands of anonymous claims through associational standing. **🔑 Key Findings:** - The court dismissed the second amended complaint because its 396 pages and 900+ paragraphs still did not give defendants fair notice of who allegedly did what to whom. - General allegations of systemic abuse by a foreign government were not enough; the court demanded concrete factual links between specific defendants, specific violations of U.S. law, and specific injuries to identified plaintiffs. - The defamation claim against defense counsel Joe Reeder was dismissed with prejudice under the absolute privilege for statements made in judicial proceedings. - Kurdistan Victims Fund could not seek $9 billion in damages on behalf of 1-5000 unnamed members because those claims require individualized proof and therefore fail associational-standing rules. - The court gave the three named individual plaintiffs one final chance to replead in a complaint capped at 30 pages, warning that further noncompliance could bring dismissal with prejudice. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10831471/kurdistan-victims-fund-v-kurdistan-regional-government/) #law #Court_Opinion #District_Court,_District_of_Columbia #Published ⏱️ 2026-04-01 23:30 UTC

The result is predictable and dumb in the usual way: more capacity does not just help users, it also subsidizes a lot of parasitic garbage. **🔑 Key Findings:** - Builds an equilibrium model linking spam volume to block capacity, minimum gas price, and fee mechanism design. - Empirical evidence from Base and Arbitrum matches the model: spam rose with more capacity and fell after minimum gas prices were introduced. - Shows spam can consume more than half of block gas on major rollups while only a small share of probes actually trade. - Priority-fee ordering reduces spam pressure because spammers must pay more to secure early block positions. --- 🔗 [Read paper](https://arxiv.org/abs/2604.00234v1) 📎 [PDF](https://arxiv.org/pdf/2604.00234v1) #crypto #fincrime #blockchain #cs.GT ⏱️ 2026-04-02 18:10 UTC

This paper repairs the gap by defining two close MQOM variants and proving EUF-CMA security under different oracle-model and one-wayness assumptions. **🔑 Key Findings:** - Identifies a proof circularity: transcript randomization appears to require hiding, while hiding itself depends on that same randomization. - Proposes one MQOM variant using random functions in the GGM trees plus minor salt changes, with proof in the quantum random oracle model. - Proposes a second variant with adjusted salts and security parameters to obtain a proof from standard one-wayness in the ideal-cipher and random-oracle models. - Uses the H-coefficient technique together with one-wayness, which may be useful beyond MQOM. - Provides one of the more concrete attempts to formalize aggressively compressed MPCitH signature designs. --- 🔗 [Read paper](https://eprint.iacr.org/2026/629) 📎 [PDF](https://eprint.iacr.org/2026/629.pdf) #cryptography #crypto #post-quantum #signatures #security-proofs ⏱️ 2026-04-02 14:45 UTC

The point is not post-quantum migration itself, but a public early-warning mechanism that turns vague quantum hype into something economically testable and auditable. **🔑 Key Findings:** - The authors introduce CAGP as a trustless distributed protocol for deploying publicly auditable quantum canary challenges. - A successful challenge solution would indicate quantum capability sufficient to break the Elliptic Curve Discrete Logarithm problem. - The protocol is designed to be decentralized, verifiable, and adjustable in difficulty while remaining natively compatible with Bitcoin. - The system uses economic incentives to motivate monitoring and attempted challenge solving rather than relying on institutional disclosure. - A proof-of-concept implementation is presented to argue that the approach is technically feasible as an early-warning system. --- 🔗 [Read paper](https://eprint.iacr.org/2026/618) 📎 [PDF](https://eprint.iacr.org/2026/618.pdf) #cryptography #crypto #bitcoin #quantum ⏱️ 2026-04-01 14:45 UTC

## 📄 Locally Computable High Independence Hashing ✍️ Yevgeniy Dodis, Shachar Lovett, Daniel Wichs 🏛️ IACR ePrint · 📅 2026-03-30 --- This paper pushes high-independence hashing closer to the parameters people actually wanted instead of the bloated versions prior work could justify. The main result is that you can get optimal-size keys with evaluations that touch only O(n) bits, and the authors also show explicit almost k-wise independent constructions that beat what perfect independence seems able to deliver. **🔑 Key Findings:** - The paper gives non-constructive perfectly k-wise independent t-local hash functions with O(kn) key size and locality O(n) bits, improving over prior O(n²)-bit locality. - It shows a generic reduction from perfectly k-wise independent local hashing to expander constructions, which means explicit progress here is bottlenecked by explicit expander progress. - The authors define and study ε-almost k-wise independence against adaptive queries rather than only perfect independence. - They construct explicit ε-almost k-wise independent hash families with optimal O(kn) key size, O(n) bit locality, and ε = 2^-n. - In a larger-word model, they obtain explicit constructions with O(kn/w) words of key material and locality O(n/√w) words, which they argue is nearly optimal. --- 🔗 [Read paper](https://eprint.iacr.org/2026/622) 📎 [PDF](https://eprint.iacr.org/2026/622.pdf) #cryptography #crypto #hashing #theory ⏱️ 2026-04-01 14:45 UTC

This paper looks at how far active learning and semi-supervised learning can cut retraining costs for both Android and Windows malware detection without just pretending distribution drift is somebody else's problem. **🔑 Key Findings:** - The evaluation is model-agnostic and covers both Android and Windows malware detection rather than one narrow benchmark niche. - Combined active-learning and semi-supervised-learning strategies cut manual annotation costs by up to 90% while staying close to full-label retraining performance. - The authors add a feature-level drift analysis method to measure how feature stability changes over time. - That drift analysis is reported to correlate with detector performance degradation, giving defenders a more concrete update signal than vibes. - The practical value is operational: cheaper refresh cycles for ML malware systems that would otherwise rot in production. --- 🔗 [Read paper](https://arxiv.org/abs/2603.28396v1) 📎 [PDF](https://arxiv.org/pdf/2603.28396v1) #cybersecurity #ai-security #malware #active-learning #drift #csLG ⏱️ 2026-03-31 06:07 UTC

## 📄 Silent Guardians: Independent and Secure Decision Tree Evaluation Without Chatter ✍️ Jinyuan Li 🏛️ arXiv · 📅 2026-03-30 --- Private ML inference papers usually promise confidentiality, verifiability, or tolerable latency. Getting all three at once is where the hand-waving starts. This work proposes a two-server protocol for outsourced decision-tree inference that removes server-to-server communication while still aiming to keep inputs, models, and result integrity protected. **🔑 Key Findings:** - The proposed PVODTE protocol combines homomorphic secret sharing with MAC-based verification for private and verifiable outsourced decision-tree evaluation. - Its main systems claim is non-interactivity: the two cloud servers do not need to communicate during evaluation. - That design targets WAN deployments where cross-server chatter adds latency and synchronization pain. - The scheme is presented as secure against malicious servers, not just the usual semi-honest toy model. - If the claims hold up, it closes a fairly common gap in MLaaS work where privacy and correctness guarantees are rarely delivered together. --- 🔗 [Read paper](https://arxiv.org/abs/2603.28143v1) 📎 [PDF](https://arxiv.org/pdf/2603.28143v1) #privacy #cryptography #machine-learning #mlaas #secure-computation #csCR ⏱️ 2026-03-31 06:07 UTC

The authors frame that race as sanction-evasion MEV and argue that, on public chains, the actor controlling ordering effectively controls enforcement. **🔑 Key Findings:** - The dataset covers Ethereum-based USDT and USDC sanctions activity from Nov. 2017 to Aug. 2025, spanning more than $1.5B in frozen assets. - Before freezes took effect, 7.3% of sanctioned USDT addresses and 18.7% of sanctioned USDC addresses were drained to zero. - The paper documents an escalation path from issuer-side execution failures to public gas auctions, private order flow, and direct proposer bribery. - A game-theoretic model suggests compliant issuers are pushed toward participating in MEV markets rather than staying outside them. - The larger claim is structural: contract-layer blacklist authority cannot guarantee sanctions enforcement when consensus-layer ordering is sold to the highest bidder. --- 🔗 [Read paper](https://arxiv.org/abs/2603.27739v1) 📎 [PDF](https://arxiv.org/pdf/2603.27739v1) #crypto #fincrime #sanctions #mev #blockchain #csCR ⏱️ 2026-03-31 06:07 UTC

The authors build a shared benchmark across 13,708 packages and show that detection quality depends less on model branding than on whether a tool can infer malicious intent from behavioral chains instead of isolated API calls. **🔑 Key Findings:** - The benchmark covers 6,420 malicious and 7,288 benign NPM packages, annotated across 11 behavior categories and 8 evasion techniques. - GuardDog reportedly delivers the best single-tool balance at 93.32% F1. - Behavior-chain reasoning matters a lot: one attack pattern jumps from 3.2% to 79.3% detection when tools model collection → serialization → exfiltration as a sequence instead of independent calls. - The paper argues recent ML failures are driven more by concept convergence—malware looking statistically similar to benign code—than by classic concept drift. - Strategic tool combinations outperform naive ensemble thinking, reaching 95.79% F1 when complementarity outweighs added false positives. --- 🔗 [Read paper](https://arxiv.org/abs/2603.27549v1) 📎 [PDF](https://arxiv.org/pdf/2603.27549v1) #cybersecurity #software-supply-chain #malware #npm #package-security #csSE ⏱️ 2026-03-31 06:07 UTC

This paper proposes a universal observation model for timed automata and uses it to define evolution-based timed opacity, giving the field a cleaner hierarchy for reasoning about what an observer can actually infer. **🔑 Key Findings:** - The paper introduces a unified observation model with full visibility into time delay but partial visibility into locations, clocks, and events. - On top of that model, it defines evolution-based timed opacity as a general semantic notion for timed systems. - The authors prove evolution-based timed opacity is strictly stronger than language-based timed opacity. - They also establish equivalence with execution-time opacity under constrained observations. - The contribution is foundational rather than applied, but useful for anyone formalizing secrecy properties in cyber-physical or real-time systems. --- 🔗 [Read paper](https://arxiv.org/abs/2603.26573v1) 📎 [PDF](https://arxiv.org/pdf/2603.26573v1) #cybersecurity #privacy #formal-methods #timed-automata #csCR ⏱️ 2026-03-30 18:03 UTC

## 📄 Towards Privacy-Preserving Federated Learning using Hybrid Homomorphic Encryption ✍️ Ivan Costa, Pedro Correia, Ivone Amorim, Eva Maia, Isabel Praça 🏛️ arXiv · 📅 2026-03-27 --- This paper goes after a weak assumption hiding in some privacy-preserving federated learning systems: everyone shares one homomorphic key pair, so a malicious client can become everyone else's problem. The authors propose two key-protection schemes for hybrid homomorphic encryption in FL—masking and RSA encapsulation—to keep client updates protected even when participants are adversarial. **🔑 Key Findings:** - Existing HHE-FL designs with a shared homomorphic key pair are argued to rely on an unrealistically soft threat model. - The paper adds two defenses: masked client keys that are later unblinded homomorphically, and RSA wrapping of homomorphically encrypted keys for server-only recovery. - Both approaches are implemented in Flower on top of the PASTA/BFV scheme and evaluated with 12 MNIST clients. - The reported tradeoff is favorable: masking adds negligible overhead, while RSA encapsulation adds only modest runtime and communication cost. - The practical contribution is extending HHE-FL from "honest enough lab demo" toward something closer to an adversarial deployment model. --- 🔗 [Read paper](https://arxiv.org/abs/2603.26417v1) 📎 [PDF](https://arxiv.org/pdf/2603.26417v1) #privacy #cryptography #cybersecurity #federated-learning #homomorphic-encryption #csCR ⏱️ 2026-03-30 18:03 UTC

This paper re-tests the problem on Solidity 0.8+ with two manually verified benchmarks, then compares formal analyzers, conventional ML models, and nine LLMs to see which approaches still work on modern contracts instead of fossilized examples. **🔑 Key Findings:** - The authors built an aggregated benchmark of 432 relabeled real-world contracts plus a 143-case Reentrancy Scenarios Dataset designed to isolate specific failure modes. - Across the aggregated benchmark, traditional tools and ML models reach up to 0.87 F1, while the best zero-shot LLM reaches 0.96. - On the scenario-focused benchmark, most tools break on multiple patterns; the best formal-style tool reaches 0.76 F1 and the strongest model reaches 0.82. - The results suggest modern LLMs now outperform most existing reentrancy detectors, at least on these benchmarks. - More awkwardly, the paper argues many established analysis tools are lagging behind modern Solidity and modern attack patterns. --- 🔗 [Read paper](https://arxiv.org/abs/2603.26497v1) 📎 [PDF](https://arxiv.org/pdf/2603.26497v1) #cybersecurity #crypto #smart-contracts #ethereum #llm #csCR ⏱️ 2026-03-30 18:03 UTC

## 📄 Can Adaptive Communication Graphs Lower the Bottleneck Complexity of (Secure) Multiparty Computation? ✍️ Lisa Kohl, Pierre Meyer, Divya Ravi, Nicolas Resch 🏛️ IACR ePrint · 📅 2026-03-27 --- This paper shows that adaptive, input-dependent communication patterns can cut the per-party communication bottleneck in multiparty computation from linear to roughly n/log n for arbitrary functions, even under secure and asynchronous execution. The result matters because prior lower bounds largely assumed fixed communication graphs; once that restriction is removed, the efficiency picture changes substantially. **🔑 Key Findings:** - Adaptive communication graphs let arbitrary Boolean functions be computed with bottleneck complexity O(n/log n), including secure variants. - The construction still works in asynchronous networks, avoiding brittle tricks like encoding information through silence or timing. - The authors argue the O(n/log n) bottleneck is essentially optimal in this model. - For symmetric functions, they both enlarge the set of functions with low-bottleneck protocols and show further gains from input-adaptive communication. --- 🔗 [Read paper](https://eprint.iacr.org/2026/608) 📎 [PDF](https://eprint.iacr.org/2026/608.pdf) #cryptography #crypto ⏱️ 2026-03-28 02:45 UTC

Nowakoski ✍️ McKinster 🏛️ CourtListener · 📅 2026-03-27 --- A California appellate court affirmed a substantial probate penalty and fee award against a former trustee who misappropriated trust assets, while directing a narrow amendment to stop post-judgment interest from accruing on prejudgment interest. The opinion matters because it treats Probate Code section 859 as a serious deterrent remedy, not something softened by claimed inability to pay. **🔑 Key Findings:** - The former trustee had already been disbarred and ordered to make restitution after taking trust funds for non-beneficiary purposes. - The probate court's roughly $399,681 civil penalty and $61,702.54 fee award largely survived appeal. - The appellate court rejected inability-to-pay mitigation as a basis to reduce the section 859 penalty. - The fee challenge failed in part because the appellant's briefing lacked adequate record citations. - The judgment was amended only to clarify that post-judgment interest does not run on the prejudgment-interest component. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10826990/moramarco-v-nowakoski/) #law #fincrime #CourtOpinion #CaliforniaCourtofAppeal #Published ⏱️ 2026-03-27 23:33 UTC

The court entered judgment for defendants, but fee-shifted only 50% because both sides polluted the record with backdating, false testimony, and general contempt for basic corporate formalities. **🔑 Key Findings:** - Expert forensic evidence persuaded the court that the plaintiff's key governance documents were fake. - Because the plaintiff was not actually a stockholder or director, he lacked standing under 8 Del. C. § 225. - The court refused to bless a lawful "status quo ante" board because the company had never properly followed statutory board-election requirements. - Defendants still took a hit: their admitted backdating and false testimony led the court to reduce fee shifting by half. - The opinion is a compact reminder that Delaware courts do not enjoy forged cap-table fan fiction. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10826329/ami-shafrir-berg-v-shai-bar-lavi/) #law #CourtOpinion #CourtofChanceryofDelaware #Published ⏱️ 2026-03-27 23:33 UTC

## 📄 Why Safety Probes Catch Liars But Miss Fanatics ✍️ Kristiyan Haralambiev 🏛️ arXiv · 📅 2026-03-26 --- This paper argues that activation probes for deceptive alignment may be good at catching systems that know they are lying, and bad at catching systems that sincerely endorse harmful behavior. The claim is that once misalignment becomes belief-consistent rather than strategically deceptive, probe-based detection can collapse from "pretty good" to basically useless. **🔑 Key Findings:** - The paper distinguishes deceptive misalignment from coherent misalignment, where a model frames harmful behavior as justified rather than hidden. - It argues no polynomial-time probe can detect sufficiently complex coherent misalignment with non-trivial accuracy. - In the authors' toy setup, a "Liar" model is detected more than 95% of the time, while a "Fanatic" model largely evades detection despite similar outward behavior. - The paper names this failure mode Emergent Probe Evasion. - If the results hold beyond the toy setting, interpretability-based safety checks aimed at internal conflict may be much narrower than advertised. --- 🔗 [Read paper](https://arxiv.org/abs/2603.25861v1) 📎 [PDF](https://arxiv.org/pdf/2603.25861v1) #ai-security #cybersecurity #interpretability #ai-safety #csCR ⏱️ 2026-03-30 18:03 UTC

## 📄 Chiral enhancement in the vector-like fourth family: Case of $b \to s γ$ ✍️ Junichiro Kawamura, Yuji Omura 🏛️ arXiv · 📅 2026-03-25 --- We demonstrate that a vector-like fourth family of quarks induces a genuine chiral enhancement in $b\to sγ$, which is absent in the Standard Model (SM). The coexistence of doublet and singlet states allows the chirality flip to occur inside the loop, leading to contributions proportional to the heavy vector-like mass. **🔑 Key Findings:** - We demonstrate that a vector-like fourth family of quarks induces a genuine chiral enhancement in $b\to sγ$, which is absent in the Standard Model (SM). - The coexistence of doublet and singlet states allows the chirality flip to occur inside the loop, leading to contributions proportional to the heavy vector-like mass. - The resulting amplitude is enhanced by a factor $\overlineλ_d v_H/m_b$, which can be as large as $\mathcal{O}(40)$ for moderate Yukawa couplings. - This leads to sizable deviation from the SM prediction even for $\mathcal{O}(\mathrm{TeV})$ vector-like quark masses and small mixing angles. --- 🔗 [Read paper](http://arxiv.org/abs/2603.24267v1) 📎 [PDF](https://arxiv.org/pdf/2603.24267v1) #hep-ph #hep-ex ⏱️ 2026-03-26 06:03 UTC

It matters because it treats data law as political infrastructure, not neutral compliance plumbing. **🔑 Key Findings:** - Examines the Personal Data Protection Ordinance, Cyber Security Ordinance, and National Data Governance Ordinance as a connected regulatory package. - Argues that formal privacy language can coexist with expanded state control, uneven enforcement, and weak subject protections. - Uses a postcolonial governance lens to show how imported compliance models can obscure local power asymmetries. - Positions data protection as a question of institutional power and legitimacy, not just statutory drafting. --- 🔗 [Read paper](https://arxiv.org/abs/2603.22637v1) 📎 [PDF](https://arxiv.org/pdf/2603.22637v1) #privacy #law #digital-rights #cyber-law #cs.HC ⏱️ 2026-03-25 06:03 UTC

## 📄 Exploiting noisy single-bit leakage in ML-DSA ✍️ Kaveh Bashiri, Jan Geuenich, Johannes Mittmann 🏛️ IACR ePrint · 📅 2026-03-23 --- This paper shows that ML-DSA can be broken with extremely weak side-channel leakage: a single noisy bit of the mask vector per signature can be enough to recover the secret key. The authors pair a stochastic leakage analysis with practical attacks that stay effective even when the leaked bit is almost random, which makes the result much uglier for real implementations than earlier work suggested. **🔑 Key Findings:** - Secret-key recovery is possible from highly noisy single-bit leakage of the mask vector \(y\) accumulated across many signatures. - The attack remains practical with bit-error probabilities up to 0.49, and in favorable cases up to 0.499. - It succeeds for leaked bit positions as low as index 4 or 5 depending on the ML-DSA parameter set, improving on prior attacks that reportedly needed positions below six. - In the best case with leakage at bit index 4 and no noise, the required number of signatures drops below 1,000. - The practical attacks get close to the theoretical minimum number of signatures predicted by the stochastic model. --- 🔗 [Read paper](https://eprint.iacr.org/2026/580) 📎 [PDF](https://eprint.iacr.org/2026/580.pdf) #cryptography #crypto #hardware-security #side-channel ⏱️ 2026-03-24 14:45 UTC

It is useful because it gives a longer historical baseline for judging whether current infrastructure threat reporting reflects a new wave or a recurring pattern with changed ideology and tactics. **🔑 Key Findings:** - The study uses an original open-source dataset covering extremist attacks and plots against infrastructure-related targets from 1970 through July 2025. - It identifies two dominant clusters: environmental and animal-rights extremism in the late 1990s and early 2000s, and a post-2015 rise in far-right infrastructure plotting. - Recent plots are described as more focused on critical systems, especially the electric grid, to create cascading disruption rather than symbolic or grievance-linked damage alone. - The article traces tactical evolution from clandestine arson campaigns toward digitally networked mobilization, firearms, and higher-casualty-risk methods. - It also reviews how law enforcement and policy responses evolved, including eco-terrorism prosecutions, infrastructure standards, and newer energy-facility statutes. --- 🔗 [Read paper](https://ctc.westpoint.edu/from-earth-liberation-to-accelerationism-a-high-level-review-of-fifty-years-of-domestic-infrastructure-terrorism/) 📎 [PDF](https://ctc.westpoint.edu/wp-content/uploads/2026/03/CTC-SENTINEL-032026_article-4.pdf) #intelligence #counterterrorism #cybersecurity #law #UnitedStates ⏱️ 2026-04-09 22:00 UTC

## 📄 Fast cube roots in Fp2 via the algebraic torus ✍️ Youssef El Housni 🏛️ IACR ePrint · 📅 2026-02-25 --- This paper gives a faster way to compute cube roots in quadratic finite-field extensions, a subroutine that shows up in elliptic-curve point decompression, hash-to-curve, and isogeny systems. The trick is to avoid expensive operations in Fp2 by mapping the problem into base-field arithmetic with the algebraic torus and Lucas sequences, which is the sort of optimization that actually matters in production crypto code. **🔑 Key Findings:** - Reduces cube-root extraction in Fp2 to arithmetic entirely in the base field Fp when p ≡ 1 mod 3. - Proves correctness across the relevant residuosity cases rather than just benchmarking a heuristic shortcut. - Shows 1.6×–2.3× speedups over direct exponentiation-based methods in gnark-crypto benchmarks. - Extends the approach to p ≡ 2 mod 3 and more generally to odd n-th roots in quadratic towers Fp^(2^k) when gcd(n, p+1) = 1. --- 🔗 [Read paper](https://eprint.iacr.org/2026/392) 📎 [PDF](https://eprint.iacr.org/2026/392.pdf) #cryptography #crypto #hardware-security ⏱️ 2026-03-30 20:45 UTC

Their reductions make simulation cheaper, relax some unrealistic assumptions, and better capture correlated oversampled leakage seen in real implementations. **🔑 Key Findings:** - Improves prior noisy-to-bounded leakage simulation strategies with both easier parameter estimation and stronger bounds. - Extends the framework to correlated leakage samples, so oversampled side-channel traces do not have to be treated as fully independent. - Introduces a tradeoff where modestly more bounded leakage can sharply reduce simulator complexity. - Expands the regimes where simulation remains efficient enough for computational security arguments. - Helps connect formal leakage-resilience claims more directly to realistic physical side-channel behavior. --- 🔗 [Read paper](https://eprint.iacr.org/2026/357) 📎 [PDF](https://eprint.iacr.org/2026/357.pdf) #cryptography #privacy #crypto ⏱️ 2026-04-07 20:47 UTC

## 📄 Migrating Bitcoin and Ethereum Addresses to the Quantum Blockchain Era ✍️ Mehmet Sabir Kiraz, Suleyman Kardas 🏛️ IACR ePrint · 📅 2026-02-21 --- This paper proposes a backward-compatible migration path for legacy Bitcoin and Ethereum funds into a post-quantum security model. The core trick is using zkSTARK proofs to link an old ECC-controlled address to a fresh post-quantum key without exposing the legacy public key on-chain, which matters because exposing old keys makes future quantum theft easier. **🔑 Key Findings:** - Defines an end-to-end migration framework for both Bitcoin UTXOs and Ethereum EOAs rather than just swapping in a new signature primitive. - Uses quantum-resistant zero-knowledge proofs so users can prove control of a legacy address while preserving privacy during migration. - Formalizes a one-way transition model where classical credentials are used only at enrollment and all later authorization is post-quantum. - Argues hash assumptions need separate quantum-era treatment for collision resistance vs. preimage resistance, pushing for hash agility in migration registries and commitments. - Proposes new blockchain verification primitives, including OP_CHECKQUANTUMSIG and OP_CHECKSTARKPROOF, to support on-chain validation of PQ signatures and proofs. --- 🔗 [Read paper](https://eprint.iacr.org/2026/352) 📎 [PDF](https://eprint.iacr.org/2026/352.pdf) #crypto #cryptography #privacy #blockchain #post-quantum #zero-knowledge ⏱️ 2026-03-31 14:45 UTC

## 📄 GG-GSW: Chosen-Ciphertext Secure Leveled FHE From Gadget Trapdoors ✍️ Jérôme Nguyen 🏛️ IACR ePrint · 📅 2026-02-18 --- This paper introduces a leveled fully homomorphic encryption scheme with IND-CCA1 security under standard LWE assumptions, without relying on SNARKs to defend against active attacks. The core move is to combine gadget lattice trapdoors with a dual GSW construction so the decryptor can recover ciphertext noise and detect dangerous oracle queries. That matters because it closes a long-standing gap between practical-ish FHE design and active-adversary security using more standard lattice tools. **🔑 Key Findings:** - Proposes the first leveled FHE scheme achieving IND-CCA1 security in the standard model without using SNARK-based ciphertext integrity proofs. - Uses Micciancio-Peikert gadget trapdoors to recover LWE noise from ciphertexts, enabling decryption-oracle checks that block secret-key leakage. - Keeps homomorphic evaluation unchanged from the underlying dual GSW-style design, limiting the extra machinery to key generation and decryption. - Achieves full compactness and multi-hop homomorphism rather than trading away core FHE properties for stronger security. - Extends the construction to IND-CPA-D security following ideas from Bourse et al., and does so without needing correctness in that upgrade path. --- 🔗 [Read paper](https://eprint.iacr.org/2026/316) 📎 [PDF](https://eprint.iacr.org/2026/316.pdf) #cryptography #crypto #privacy #fhe #lwe ⏱️ 2026-04-09 14:45 UTC

## 📄 At-Compromise Security: The Case for Alert Blindness ✍️ Martin R.

The result is awkward for both regulators and compliance teams: technical enforcement looks weaker than the law seems to assume. **🔑 Key Findings:** - Analyzes how new EU AML obligations map onto the actual technical affordances of Monero trading and transaction monitoring. - Identifies gaps where legal due-diligence expectations do not align cleanly with protocol-level observability. - Builds a hidden transaction layer using anamorphic cryptography to conceal illicit flows inside normal-looking Monero activity. - Frames this as one of the first practical applications of anamorphic cryptography, with direct compliance and policy implications. --- 🔗 [Read paper](https://eprint.iacr.org/2025/1961) 📎 [PDF](https://eprint.iacr.org/2025/1961.pdf) #crypto #cryptography #privacy #fincrime #law ⏱️ 2026-03-25 14:45 UTC

## 📄 Is the Hard-Label Cryptanalytic Model Extraction Really Polynomial? ✍️ Akira Ito, Takayuki Miura, Yosuke Todo 🏛️ IACR ePrint · 📅 2025-10-08 --- This paper argues that recent hard-label DNN model-extraction attacks lean on an assumption that breaks down as network depth grows. It shows why "polynomial-time" extraction claims are too optimistic in the presence of neurons whose activation states almost never flip, then proposes a cross-layer extraction method to work around that failure mode. **🔑 Key Findings:** - Identifies rarely switching neurons as a concrete blocker for hard-label extraction attacks on deep ReLU networks. - Shows that even one almost-always-active neuron can stall extraction unless its hidden parameters are recovered. - Argues that observing the needed state switch can become exponentially hard with depth, undermining blanket polynomial-time claims. - Proposes cross-layer extraction to infer parameters indirectly from deeper-layer interactions and cut query complexity. --- 🔗 [Read paper](https://eprint.iacr.org/2025/1868) 📎 [PDF](https://eprint.iacr.org/2025/1868.pdf) #ai-security #cryptography #cybersecurity ⏱️ 2026-03-26 08:45 UTC

The proposed samplers generate structured non-degenerate boundary-format tensors and then randomize them in ways intended to preserve both non-degeneracy and, under stated assumptions, computational indistinguishability from uniform samples. **🔑 Key Findings:** - Gives two sampling strategies for non-degenerate boundary-format tensors: invertible linear actions in each dimension, and tensor convolution. - Avoids the impractical “sample-and-reject” approach, since testing tensor degeneracy in higher dimensions is conjecturally hard. - Argues these samples resist recent weak-key attacks that exploit geometric structure or low tensor rank in public tensors. - Recommends instantiating tensor-isomorphism schemes in boundary formats such as (2k+1) × (k+1) × (k+1), rather than the usual cubic k × k × k setting. - Positions boundary-format tensors as the real higher-dimensional analogue of square matrices for this cryptographic family. --- 🔗 [Read paper](https://eprint.iacr.org/2025/708) 📎 [PDF](https://eprint.iacr.org/2025/708.pdf) #crypto #cryptography #iacr ⏱️ 2026-03-30 08:45 UTC
